When I came to Deno, I was a developer that had retired young in 2000 (I'm 75).
I avoided tech for many years, and took up wood-working as a hobby.
My only computer use was browsing for tools, materials and woodworking articles.

Sometime In 2014, I was approached to do a project for a California NGO working in Cambodia.
One of their engineers had seen one of my graphical real-time desktop apps running in a Toyota plant.
They needed something similar for the detection of underground Unexploded Ordnance (UXO).
I volunteered, and suggested the use of a three-tiered solution.
